:checkbox Selector

checkbox selector

$( ":checkbox" ) is equivalent to $( "[type=checkbox]" ). As with other pseudo-class selectors (those that begin with a ":") it is recommended to precede it with a tag name or some other selector; otherwise, the universal selector ("*") is implied. In other words, the bare $(':checkbox') is equivalent to $( "*:checkbox" ), so $( "input:checkbox" ) should be used instead.

Additional Notes:

Because :checkbox is a jQuery extension and not part of the CSS specification, queries using :checkbox cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. For better performance in modern browsers, use [type="checkbox"] instead.
